Question

A GRASS module crashed and left the sqlite database locked. How can I unlock the sqlite database?

Answer

Make sure the database file isn't granted read-only permissions and/or that the database isn't already accessed by another application. E.g.:

$ ps aux | grep sqlite
martin   21118  0.0  0.3  21456  3176 pts/1    S    Dec04   0:00 /usr/local/src/grass6_devel/dist.i686-pc-linux-gnu/driver/db/sqlite

To kill the process:

$ kill -9 21118
